Changing the Paper Size in the Paper Tray
To load longer sizes of paper, such as Legal-sized paper, you
need to adjust the paper guides to extend the paper tray.
1 Pressing and unlatching the guide lock, slide the paper
length guide out completely to extend the paper tray to its
full length.
2 After inserting paper into the tray, slide in the guide until it
lightly touches the end of the paper stack.
3 Pinching the paper width guide as shown, move it toward
the stack of paper until it lightly touches the side of the
stack.
